Concept Check
1. The alternate expansion and contraction of surface material caused by freezing and thawing, or wetting and drying lifts particles at right angles to the slope, and thawing or drying allows the particle to fall back to a slightly lower level. Each cycle therefore moves the material a short distance downhill.
2. Solifluction occurs during the summer and winter. Solifluction is common in regions underlain by permafrost, permanently frozen ground that occurs in Earth’s harsh tundra and ice-cap climates. In a zone above the permafrost called the active layer(thaws in summer and refreezes in winter). During summer water is unable to percolate into the impervious permafrost layer below, as a result the active layer becomes saturated and slowly flows.

Give It Some Thought

1.Roots of plants can promote mechanical weathering by pushing into a rock, causing root wedging, widening fractures, and exposing it to elements that could further weather rock. Chemical weathering can be caused by roots, fungi getting into fractures, or encrust a rock produce acids that promote decomposition. Plants, however, prohibit erosion because the roots of the plants hold the soil together and help prevent soil from being moved by water, wind, rain.

2. Chemical weathering is predominant, basalt will weather more rapidly, basalt does not contain quarts like granite, so the fine grained basalt will weather faster.

3. The material does not satisfy the definition we use for soil on earth because earths soil is composed of a combination of mineral and organic matter, disintegrated and decomposed rock, humus, the decayed remains of animal and plant life, water and air.

Biodiversity- BIG IDEAS
• All living things can be classified according to their anatomical (physical appearance) and physiological (how our organs function) characteristics
• Human activities affect the diversity of living things in ecosystems
Homework Notes- Taxonomy, Classification and Binomial Nomenclature
• Classification is the grouping of organisms based on a set of criteria that helps to organize and indicate evolutionary relationships (it can also be sued to classify anything- e.g. baseball teams…

B2.1 Cells and Cell Structures
Summary
All living things are made up of cells. The structures of different types of cells are related to their functions. To get into or out of cells, dissolved substances have to cross the cell membranes.
Cells
• Cells are the smallest unit of life.
• All living things are made of cells.
• Most human cells, like most other animal cells, have the following parts:
o nucleus
o cytoplasm…

EVIDENCE OF EVOLUTION
1. Outline the impact on the evolution of plants and animals of:
- changes in physical conditions in the environment
- changes in chemical conditions in the environment
- competition for resources
Changes in the environment of living organisms can lead to the evolution of plant and animal species. These environmental changed in condition may be physical, such as temperature changes, or chemical, such as changes in water salinity. Change may also…

Introduction
Finance – the discipline concerned with or the study of the efficient acquisitions and utilization of capital
Study of the creation of value as it is measured in monetary terms
Capital – wealth that is used to generate more wealth
Value – the sum of all future cash flows expected to be generated by an asset (real or financial) or an entity discounted to the present time at an appropriate cost of capital
Arbitrage – the ability to increase you wealth without…

B1- Human Biology
Summary
Diet and Metabolic Rate:
Regular exercise and a balanced diet are needed to keep the body healthy. Too little food leads to a person being underweight and prone to certain types of illness, while too much food and not enough exercise leads to a person being overweight and other types of ill health.
Carbohydrates- to release energy
Fats- to keep warm, and release energy
Protein- growth, cell repair, cell replacement
Fibre- to help your digestive system
Vitamins and…

Topic 1: Cell Biology
1.1 Introduction to cells
Outline the cell theory and the evidence supporting it.
1. All living organisms are composed of one or more cell.
Robert Hooke (1665) discovered cork cells through a microscope.
(few years later) Antonie Van Leeuwenhoek saw first living cells ‘animalcules’.
Matthais Schleiden (1838)stated that plants are made of ‘independent separate beings’.
2. Cells are the smallest units of life.
No living entity composed of at least one cell has been found.
Cells…
